TO ALLWIIOI IT MAY CONCERN:

i De vit 'known that we W'. II. IIARTAIAN and A. Ii. 1l. PICI-IERT; ofFostoria, in the count-y of Seneca, and State of'4 Ohio. have infentedcertain new and useful Improvements in Carriage-Shaft Couplings; and wedo hereby declare that the following is a full und complete descriptionof the construction and operation of the same, reference being had tothe accompanying driwiugs, making a part of this specificatioi'i, inwhich- Figure l is a top vien' of the coupling. L

Figure 2 is an under -Side view.

Figure is a side view.

Lilie letters oi' reference refer to like parts in the' views.

A, fig. 1, is the reach, to which the shafts are attached. B, theheadof' the reach, is provided with a pivot, C', one at each side. Ihis headis made to [it between the arms of the stay D, and moves upon the pivotswhich are fitted to thesl-ots cut iu the sides of the stay, as shown intig. o. In order to prevent the pivots from being displaced on thebackng'oi` the carriage the head of the reach is backed up by the blockof rubber E, which is placed between thc head of' the reach and backofthe stay. F isa guard, which consists of a piece of brass or other metalinterposed between the rubber and'head, whereby the rubberis'preventedfrom wearing by the friction of the head. It also serves toAprotectthe rubber, and gives greater security to its position. Thisrubber is secured to the stay by the bolt G, which is passed through theguard and rubber, and screwed into the clip-har II. I is a band, which,together with the` bar II, forms the clip, by which the coupling isfastened to the axle of the carriage by passing the band over the axle,and its threaded ends projected through the bar H, and then securedV bythe nuts J.

The usual manner of coupling the shafts to a carriage is by passing abolt through the stay and the head of the reach, and their securing thesaine with one or more nuts. These nuts often become loose and t'alloff, and the thills in consequence become detached, to the danger ofthose who may be in the carriage, by the team becoming frightened, 53e.;but by this method of coupling it is impossible for the shafts to becomedetached without special means applied for that purpose, there being nonuts to fall oil' nor bolts to drop out; hence this coupling is unichsafer than the old one. The bolts in the old coupling soon become looseby the constant jarring and wearing yof the bolts and bolt holes, andwhen thus loose produce a continual noisy rattling, and are more liableto break by any sudden strain than if they were tight. In the couplingunder consideration these difiicultes are avoided by the action of therubber, which, atall times, keeps the pivots close to the slots in whichthey move; hence, the pivots can never get loose, or the thills becomedetached.

lVha-t we claim as our improvement, and desire to secure byLcttersPateut, is-

- 1. lhe rubber block E, provided with the guard F, and secured,- bymeans of through-bolt or -screw G, to the detached or separa-teelip-barH, in combination with the slotted stay D, secured to clip I, in themanner shown and described.

2. The head B, pivots C, and slotted stay D, in combination with theclip I, guard F, screw G, and rubber E, when the several parts areconstructed and arranged in relation to each other, in the manner andfor the purpose described.
